The Brooklyn-native had been receiving chemotherapy treatments.Though Murphy had long been on the comedy circuit, he rose to national prominence in 2003 as a co-star on Dave Chappelle's eponymous "Chappelle's Show." Murphy was also a writer for the sketch comedy show.

Murphy tweeted Wednesday morning before TMZ first reported his death. The message starts with "Rise & Grind," an opening used frequently by Murphy on his Twitter account that is often followed by a motivational message.

"Things may come to those who wait, but only the things left by those who hustle," the comedian went on to write, mistakenly attributing the phrase to Abraham Lincoln — a common error.

The post was taken down later in the day.

Members of the entertainment industry were shocked by the sudden loss and shared their sadness via social media.
